WATER-HEATER.

Specification of Letters Patent.

Application filed May 18, 1910.

Patented Mar. 5, 1912.

Serial No. 562,036.

To all whom it may concern Be it known that I, CORNELIUS A. RYER- soN, a citizen of the United States, residing at Toronto, in the Province of Ontario, Canada, have invented certain new and useful Improvements-in Water-Heaters, of which the following is a specification.

This invention relates to devices for utilizing waste heat of flue gases for the pur pose of obtaining hot water and steam, and has in view the gain of a maximum of heat with a minimum of obstruction in the flow of the flue gases.

The device is intended particularly for use with ordinary household stoves and furnaces, and it consists essentially of a length of stove pipe provided with a set of heating pipes, arranged so as not to interfere with the draft, said pipes being provided with suitable connections for downflow and up flow of water or steam, as Will be seen from the detailed description, the claims and the drawing, in which Figure 1 is a cross-section of the device, on the line XX of Fig. 1, and Fig. 2 is a longitudinal section partly in elevation.

Referring to the drawing there is shown a section of a smoke pipe, A adapted to be placed horizontally or approximately so. In the upper portion of this is located a number of pipes F, connected by segmental annular heads E, the latter carrying nipples G and D extending through the smoke pipe A. The pipes F and heads E are arranged in the upper portion of the pipe where the heat is the greatest, the lower portion of the pipe being unobstructed, so that the gases when cooled can readily passofl. The heads E do not quite touch the smoke pipe, and hence there is circulation of hot flue gases all around them.

In order that the heater may be cleaned whenever necessary a cleaning door G is provided in the lower portion of the pipe section A.

The construction of this form of water heater is simple and durable and it is very eflicient without materially interfering with the normal heating operation of the stove or furnace from which the hot waste gases emanate.

What I claim as new is 1. In a water heater the combination of an approximately horizontal smoke pipe section, a series of water heating pipes located therein adjacent its upper surface, approximately semicircular heads connected to the ends of said pipes and communicating therewith, and nipples communicating with the water spaces of the said heads at their highest points, extending-through the upper portion of said smoke pipe section and attached thereto.

2. In a water heater the combination of an approximately horizontal smoke pipe section, a series of water heating pipes located therein adjacent its upper surface, approximately semicircular heads connected to the ends of said pipes and communicating there with, and nipples on the convex surfaces of said heads intermediate of their ends extending through the upper portion of said smoke pipe section and attached thereto.

Toronto this 5th day of April 1910.
